Part 1: Selection of a problem to study and an initial hypothesis.
The curiosity of friction between two objects has always been the main topic of different physicians. This is a case that has always been of interest and most of the physicians would like to find out the friction relationship between objects. The Topic that will be studied is the Coefficient of friction. First, the coefficient of friction is the value that tends to indicate the relationship between the forces of friction between two different objects. It is believed that a wooden block and a wooden plane have got a unique coefficient of friction. Therefore, the purpose of this study is measuring the coefficients of static and kinetic friction between a wooden block as well as a wooden plane. It is good noting that friction is the force known to resist the relative motion of one surface that is in contact with another. Generally, there are two known types of forces. The first one is the static friction and the second one is kinetic friction. In most cases, the kinetic friction is always less than the maximum form of static friction. Therefore, this experiment will measure the friction force between the slowly sliding block that is tilted and the wooden surface. From the data obtained from the experiment, one will now be able to obtain the coefficients of static as well as the kinetic friction.
Part 2: Review current research knowledge.
There various ways on which one can conduct a current review but for this study it only used online sources and texts books that have well covered the topic. There is a lot of helpful information on the internet that can help one to get information that will support the one in the text. Additionally, here is a list of some sources that seemed to back up my hypothesis.
Delegate your assignment to our experts and they will do the rest.

Sandeep, C., & Senetakis, K. (2018). Effect of Young's modulus and surface roughness on the inter-particle friction of granular materials. Materials, 11(2), 217.
The criteria that have been used in the selection process of these sources is that they do not have to be more than five years old in order for them to meet the qualification. This makes the information to be up-to-date and it will avoid misleading those interested in the current review. The other qualification is that it has to be from qualified researchers who have qualified in this field as their profession. This criterion makes the source credible and reliable for qualified information that is related to this field. Clearly, the sources are very credible and they have supported my hypothesis and it appears to be correct. This means that there is no need for modifying the hypothesis any further. Therefore it is confirmed that indeed there is a coefficient of friction between two wooden surfaces. There are no gaps in the current research that tends to offer an opportunity for further research since everything has been covered in the current research. This proves that the hypothesis is correct.
Part 3: Write a research plan based on the results of parts 1 and 2 above.
The plan that will be used to test the initial hypothesis will be a laboratory test that will help confirm this hypothesis. This laboratory experiment will help in testing the initial hypothesis. The first step in testing the hypothesis will be to present the list of all possible hypotheses that will be tested. Next will be to make predictions for each and every hypothesis presented where one will ask themselves what would be true if indeed the hypothesis is true. The third step will be writing the experimental procedure that will be followed when conducting the experiment. Then the step that will follow would be the identification of dependent and independent variables followed by designing the experiment. The other step will be defining the experimental group and the control group. The experimental group involves trials where the independent variables are changed. On the other hand, the control group is where the independent variable is left in its constant state in all the trials involved.
The types of equipment that will be required for this experiment include 6 blocks of different materials and put them on a wooden ramp. The time required for gathering the data is only a period of one to two days and all the credible data will have been collected. Some of the confounding issues that can occur when conducting an experiment include the fact that a researcher may conclude in favor of their own hypothesis. Some of the researchers tend to report non-existing data which is known as data fabrication. Another confounding issue that can affect is the act of eliminating the data that tends to not support their hypothesis. There is a simple way of making sure that all the mentioned issues above are addressed. This can be done through being honest with yourself and adhering to the core values and morals of a professional researcher. The following is a list of credible sources that gives a clear outline of the issues above. The data can well be presented with the use of a graph that will have an X and Y axis with a best-fit line between the points by pulling down the graph menu to the regression line.

This is a credible source since it has an author who is who is qualified as well as a publication date which is Feb 15, 2015.
